OF ROCHESTER, NEW YORK, A CORPORATION OF NEW YORK BEVERAGE DISPENSER Application filed October 23, 1928. Serial No. 314,343.

This invention is in the nature of improvements on the apparatus disclosed in Patent No. 1,7 08,212 to Leon L. Benham, for beverage dispenser, and relates to a beverage dispenser, with particular reference to the type of apparatus comprising a transparent disprincipal object to afford means for prevent-t ing passage of air through the dispensing tube to the interior of the displayreceiver when the tube is out of dispensing position. V

the dispensing tube in dispensing position;

In a more specific aspect, the invention has for its purpose to provide a simple, practicable, and efficient form of dispensing tube which may be of glass or similar material, and has in cooperation therewith a valve-like member or closure that functions automatically to close the passage through the dispensing tube when the latter is out of dispensing position so as to prevent drawing air into the interior of the display receiver during the time when the beverage is circulating and not being dispensed.

To these and other ends the invention consists in the construction and arrangement that will appear from the following description when read in conjunction with the accompanying drawings, the novel features being pointed out in the claims following the description.

In the drawings:

Figure 1 is a side elevation of a beverage dispenser showing one embodiment of the invention applied thereto and with the dispensing tube out of dispensing position;

Figure 2 is an enlarged side elevation with parts broken away and illustrating the dispensing tube in its innermost or dispensing position;

Figure 3 is an enlarged sectional view through the dispensing tube when out of dispensing position, as shown in Figure 1;

Figure 5 is a sectional view of a modified form of dispensing tube, out of dispensing position; i

Figure 6 is a similar sectional view of the structure shown in Figure 5 with the dispensing tube in dispensing position;

Figure 7 is a similar view of a further modified arrangement of dispensing tube when out of dispensing position;

Figure 8 is a view similar to Figure 7 with the dispensing tube in dispensing position;

Figure 9 is a similar sectional View of another modification with the dispensing tube out of dispensing position;

Figure 10 is a view similar to Figure 9 with Figure 11 is a similar view of a further modiication with the dispensing tube out of dispensing position;

Figure 12 is a view similar to Figure 11 with the dispensing tube in dispensing position, and V Figure 13 is a sectional view on line 13-13 of Figure 12.

Referring more particularly to the drawings in which like reference numerals throughout the several views indicate the same parts, 1 designates a transparent display receiver suitably mounted in the base 2 which is supported on a cabinet 3, while 4 is a beverage reservoir located and adapted to be refrigerated within the cabinet 3. 5 is a motor operating a pump 6 to force the beverage from the reservoir through a suitable conductor and the discharge pipe 7 into the display receiver, preferably with a fountain effect, as shown, although the beverage may be otherwise discharged into the display receiver from which it feeds back by gravity through another conductor to the reservoir 4, thus maintaining a continuous circulation between the reservoir and the receiver.

Mounted in a wall of the transparent receiver 1 is the dispensing tube that is movable into the path of the stream of beverage, to thereby divert the same to a point outside the receiver. Referring in detail to the arrangement shown in Figures 1 to 4 inclusive, 100

11 designates the dispensing tube having an outlet 12, and an inlet opening 13 adjacent to its inner end. The dispensing tube is slidable endwise in a housing 14 that is secured to a wall of the transparent receiver by suitable threaded collars 15 and 16. The dispensing tube, which may be of glass or other similar material, is formed with an enlargement at 17, and 18 is acollar arranged on the tube adjacent said enlargement 17 ivhich limits outward movement of the col- A spring 19 is arranged in the recess 20 of the housing 14 and engages the inner end of the collar 18 at one end and a shoulder 21 at the opposite end, thereby acting to normally hold the dispensing tube in its outermost position, as shown in Figure 3, where it is out of dispensing position. At its inner end, the dispensing tube is provided with a plug 22 which carries a head or flange 23 adapted to make contact with the end of the housing 14, as shown in Figure 3, when the dispensing tube is out of dispensing position, and thus efiect a closure of the housing, the inlet opening 13 being then arranged Within the housing. In this manner passage of air inwardly through the dispensing tube to the interior of the display receiver is effectually prevented when the latter is out of dispensing position.

In some cases, the-dispensing tube maybe constructed as shown in Figures 5-and 6, in

which the dispensing tube is formed with its inner end closed, as shown at 24, and arranged to form a sufficiently tight engagement with the housing 25 so that when the tube is out of dispensing position, as in Figure 5, the passage of air through the tube to the interior of the display receiver in any substantial amount is effectually prevented.

In Figures 7 and 8 there is illustrated another embodiment of the invention wherein the dispensing tube 26 is formed with a chamber 27 and a seat 28, while 29 designates a ball'valve that engages said seat 28 and closes the passage to prevent ingress of air when the dispensing tube is out of dispensing position, as shown in Figure 7, and when moved into dispensing position, pressure of the beverage forces the valve 29 outwardly and it floats in the chamber 27 during the dispensing operation, as shown in Figure 8.

In Figures 9 and 10 there is illustrated an additional modified arrangement that includes a stationary dispensing tube 31 having an outlet 32 and open at its inner end, as designated at 33, see Figure 10. The tube 31 is held within a bushing 34, and 35 designates a housing slidably arranged upon the inner end of the dispensing tube and including an inlet opening 36 positionable in the path of the beverage discharge and a gasket 37 for engaging and closing the opening 33 at the inner end of the dispensing tube, as shown in Figure 9, when moved out of dis pensing position. In this instance, the operation of dispensing a beverage is brought about by sliding the housing 35 inwardly from the position shown in Figure 9 to that shown in Figure 10. To accomplish this, the housing has attached thereto a suitable eX- tension or rod 38 carrying at its outer end a handle 39, while 40 is a spring cooperating] between the handle 39 and the bottom of a pocket 41 in which the spring is mounted, and operating to normally hold the housing in its outermost position as in Figure 9. lVhen dispensing, the operator presses the handle 39 inwardly against the action of spring 40, the parts then assuming the position shown in Figure 10, and upon releasing the handle 39, spring 40 returns the housing to normal position in whichthe dispensing tube is closed and passage of air to the inflowing outwardly through the tube moves the ball 45 away from the seat 43 and passes thence outwardly around the ball, the latter being-limitedin its outward movement by the inward projections 44.

While the invention'has been herein dis closed with reference to certain detailed arrangements, it is not confined to the particular structures herein set forth, and this application is intended to cover such other departures or changes as may come within the intent of the improvements or the scope of the following claims.
